Sylveon (Japanese: ニンフィアNinfia) is an unknown-type Pokémon and also an evolution of Eevee. More information about the Pokémon is currently unknown.
Sylveon is a Pokémon with cream coloured fur on most of its slender body and a reddish tail. There are two bow shaped and scarf-like objects around its body. It has four legs, each one a pink color - like the tail - and three toes on each. It also has two large blue eyes and long pink ears.
Like the other Eeveelutions the name might give us some clues for his element. It could be Bug (because of the move Silver Wind) or still Steel (because silver is a metal). Others point to a move used by Sylveon in a game trailer resembling Sky Attack or Brave Bird, hinting at it potentially being a Flying-type.
